to provide a duplex column of the type wherein fiat plate glass is usedfor each columnfwhich is constructed so that both colpositions.

umns are disposed at a convenient angle whereby they may be viewed fromdifferent A column of this character is adapted especially for use uponlocomotive boilers so as to permit both engineer and fireman to read theglass at all times.v

A further object of the invention is to provide a duplex column which iscomposed of the fewest'possible parts, and which is compact and durableso as to withstand the considerable jar incident 'with its use.

A still further object is the provision of a device of this characterwhich constructed so that there is no danger, of either glass becomingblown out by excessive boiler pressure. v

The invention consists in the features of i construction, lcombinationand arrangementof parts, hereinafter fully described and 4 claimed,reference being had tothe accompanying drawings, inwhieh:

Figure 1 is a front elevation of lthedevice; Fig. 2 is a rear elevationof the same;

Fig. 3 is a longitudinal sectional view taken through theY device; Fig.4 is a transverse sectional view taken therethrough, and Fig.,l

5 is a transverse sectionala view of the body ofthe device alone. i

Referring' to the drawings, it will. be seen -that my improved duplexcolumn comprises a body 1 whichl is formed with wings 2 and 3 disposed,as shown, at right angles, but

which `may be disposed at any convenient angle. The body 1 is providedat 'its extremities with tubular portions 4f and 5 adapted to beconnected to a boiler as shown, or in any other suitable well knownmanner. Each Awing of the body is provided in its outer face with alongitudinal recess '6. of rectangular configuration for the receptionof a -portion of the corresponding gage glass 7, and is further providedwith a longitudinally extending, semi-cylindrical groove 8 in itsinwardly bulged ortion 9 in communication with the` sai recess `6. Eachgroove 8 extends for nearly the enti-re length of the correspondingrecess, terminating at a short distance fromthe ends of the recess.

The longitudinalopening 10 of each tubuylar pbrtion of the body 1 isconnected by means of the outwardly curved, branch passage-ways 11 withthe adjacent ends of the respective wing grooves 8. The concave wall 12of each branch passage-way 11 serves4 to retaird the motionjof the wateras caused by excessive steam pressure, andfurther serves to direct thesame against the gage glass 7 at rig-ht angles thereto and at a pointsubstantially opposite the adjacent end por-V tion 13 of thecorresponding clamping. memvwo ber 14,. so that undue strain will notcome to bear upon the exposed portion thereof.

`Each clamping member letyis adapted to be secu-red against the outerface of one of the body wings by means of the clamping bolts 16, andcompletely covers the same, its end portions being rounded as at 17 toconform to the shape of the rounded ends of the wing. Each clampingmember is cut away centrally as at 18 to providea longitudinal viewopening in communication with the elongated recess 19 provided in theinner face of the said member for. the

reception of the outer portion of the coryopemngs 22 provided ingtheclamping member in communication with the extended recess portions 20,-inwardly with respect to the fulcrum edges 21, the inner ends of these.bolt-s being removably threaded into the re'- cesses 23 provided in thebody wing. Nuts 24 arethreaded upon the outer ends of the bolts 16 andare engageablejwith the rounded outer face 25 of the clamping member,inwardly with respect to the ulcrum edges 21 thereof, so that, when thesaid nuts are tightened upon 4the said bolts, the. inner engaging edgesor jaws 26 of the clamping member will be clamped against the asbestosgasket 27 interposed between the same and the outeredges of the gageglass. A

rubber gasket 28 is interposed between the inner edges of the gage glassand the inner Wall ofv the wing recess surrounding the correspondingWater groove. It is to be understood, that the metal of which theclampingmembers are constructed is to be of such nature that the innerclamping edges of the clamping member may be sprung inwardly wwhen theclamping members are tightened, and may be of brass, aluminum or thelike.

From the foregoing description, taken in `connection with theaccompanying drawings, it will be apparent that I have provided a simplyconstructed and emcient gage glass column of the duplex type which 'isadapted to meet all the requirements of usage, which will retain itsrespective gage glasses indefinitely and which may be used convenientlyin connection with any type of boiler.

IVhat I claim is:

l. In .a'device of the class described, a

opening into the adjacent ends of the water grooves. f

2.`In a body having lateral Wings, provided in their outer faces withlongitudinal gage glass recesses and with longitudinal Water grooves inthe inner Wall of said recesses, and a tubular 'connecting portionprovided upon veach end of said body having diverging,

outwardly curved `passage-Ways opening into the adjacent ends of theWater grooves.

8. In a device of the class described, a body having lateral Wings,provided in their outer faces with longitudinal gage glass re.

cesses and. with longitudinal water grooves in the inner Wall of saidrecesses, a tubular connecting portionprovided upon each end of saidbody having diverging passage-ways opening into the adjacent ends of thewater grooves, a flat gage' glass adapted to be positioned Within eachwing recess, and means f by which each glass may be secured in position.

In testimony whereof I afiix my signature in presence of two Witnesses.
